The Chicago White Sox have a phenomenal young group of players. Some are at slightly different positions contractually but they are all around the same age. This is a core that will be the main focus of the team as they try to compete for multiple years in a row. They have done a really good job of locking these guys up for the future but they still have a few more to go.
There will always be guys they need to extend as the years go quickly. They also have new talent coming in and out each year so they just need to make sure their spending money is going to the right places.
